Constable Gene DeForest said Jamie Teran, 36, and his son dropped 30 feet and landed upside down on the rocks below. The son was able to crawl out with minor injuries, but the dad suffered a leg injury and was flown to a Houston hospital in critical condition.

Police Reporter notes this was the area’s second such crash in several months. A boy in a golf course crashed through the railing earlier, but he was uninjured.
